Today we will talk about just how a laser rangefinder functions. The distance to an objective is calculated by a rangefinder by the rebounding of a laser light beam off the object to be ranged. The time it takes for the laser light beam to reach the target and return is measured by a high speed digital clock. This time that commonly takes less than one second, is then computed by the rangefinder and displayed as a distance on the rangefinders build in screen.

Rifle Rangefinders:
Rangefinders designed specifically for rifle hunting are often of higher magnification than other hunting rangefinders. While many of these rangefinders designed for rifle hunting do a scan mode, many lack an angle compensation feature that is found on a lot of other hunting rangefinders. Some of these models are also of a flatter design and are held horizontally like binoculars, instead of vertically like a monocular. This enables the hunter to hold the unit steady easier for long range targeting.

Being waterproof is another advantage that some rangefinders have over others. When you are out in the woods for an extended period, you never know what type of weather you will be exposed to. Devices can be costly, and you don’t want them to be ruined by rain and other adverse conditions. The same is true if you accidentally dropped your rangefinder near a puddle of water.
Rangefinders for hunting offer you many benefits when it comes to making a kill. Not all of them offer the same benefits, however, so you must know what to look for when purchasing a rangefinder. Size and weight are important considerations if you want to be able to carry this gadget properly. A camo finish will allow you to sneak up on your prey without being detected. Waterproof hunting rangefinders are also a good choice so that your device is not damaged in the rain.
